| Summary: | This study presents the mechanical properties of Al–12% Si matrix composite reinforced (which can
used in light devices and energy storage) by various amounts of Titanium Nitride (TiN) particles.
Macrostructural studies have shown near uniform distribution of TiN particles in the matrix. The mechanical
properties such as hardness and wear resistance are observed to be increased considerably compared to the
matrix composite. The wear behaviour was investigated using a pin-on-disc wear testing machine with varying
parameters such as normal load, reinforcement’s percentage and track velocity. The results suggested that the
reinforced Al-12Si matrix composites showed significant improvement in their wear resistance accordingly
with increasing the reinforcement’s percentage at different conditions.
The microstructural study of the
composites before wear test showed uniform distribution through the cross-section of the specimens and finer
surfaces than matrix composite after wear test |
